FASTENER-SUPPLYING DEVICE.

Application filed February 28, l1921. Serial No. 447,997.

provements in FastenenSupplying Devices, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters yon the drawings indicating like parts in the several figures. n y

This invention relates to mecha-msms foi" Y supplying fasteninggand is illustrated as embodied in a mechanism. for supplyingV vtacks to' a hand tacker of'usual type'used in the manufacture of shoes.4 -v

In one form' of such mechanism, commonly used 'in the lasting of shoes on a bed laster, tacks are automatically fedfrom a hop-v per into a raceway which feeds them to a co-operating raceway in the hand tacker, and a detent is provided at the end of each raceway, to retain tacks` thereinv when the hand tacker is disconnected from the raceway on the feed mechanism; these detents being swung to idle position when the hand l.

tackscaught by the spill pan are ordinarily junked. v f v An obliect of this invention,accordingly,

is the improvement of mechanisms ofthis character so as to prevent the vprotrusion of the Shanks of fastenings from the feeding racew'ay, and an important feature thereof is to be found in a novel organization comprising an improved form andarrangement of 'detent adapted to restraink fastenings in a raceway, and means to move itlongitudinalu` ly thereof to push the fastenings back from the open end. v

Further features are to be found in varions combinations and specific construcvendmost tack.y

'tions of parts hereinafter described and` claimed, and shown in the' accom'panyingr drawings, in whichs Fig. l is a side elevation of a rhand tacker removably mounted on a Vfeeding "raceway,

2 is an enlarged side elevation, and Fig. 3 is 'a top plan view, showing the joint between the Jrfa-cker and the raccway;

Fig. 4 is a side elevatiomand Fig. 5 is al perspective, of the end of the tacker raccway; and r l v Fig. 6 is a perspective of the detent and its actuating mechanism.

A'. hand tacker A10, of; usual construction,

.is lillustrated,in Figs.` 1' to 3 as removably connected to the lower endl of a racewayZO,

from which it is` supplied lwith tacks. A hook 12on the tacker is supported, by a pin 22 =on the raceway, and entersbetween plates 24, to aline the raceway 14 of the hand tacker with the feedingv raceway 20. vWhen the tacker is removed, a detent lGcloses the 11p-- per end of raceway 14; when it is replaced, detent 16 `ismoved to idle position by a cam surface 26. A pinl 17 is rigidly mounted on theracewayl4, as shown in .detail in Fig. 5, by a support 18, held byV a clamp screw 19.

As shown clearly in Fig. 6, av fingenlike detent 30 is provided to close the'lower end of raceway 20 when the-tacker 10 is removed.

This detent is in the forni-of a bell-crank; n leveiyan'd has a ypointed end 32 to project y into the raccway7 tok enga-ge the shankof the lt 1s provided lwith a slot 34, which engages a' fulcrum 36 carried by a Viii-.ed bracket 38. A; spring 40 engaging the fulcrum 36 and a pin 42 carried by the detent, constantly urges point 32' intothe raceway. The bracket 38 is secured to racewa",T 2O by a bolt and nut 44.

The detent 3,0 is provide-d rvwith a second slot 46 at right angles to the flrst'and en gaging a pin 48carried by a lever 5() fulcrumed on bracket 38 at 52.l Lever 50vis rocked lin one direction by a Aplunger 54 carrying a pin 56 which enters a slot 58 in lever 50. It is rockedin the other direction b v a spring 60, l.which constantly urges plunger l54 outwardly.y
